CEVAP:

As a private law contract, validity of an employment contract is dependent on the existence of validity conditions such as legal capacity and the subject matter of the contract being in conformity with the imperative legal rules, morality, public order, and personality rights and not impossible to be realized. Just as any other legal transaction, employment contracts that are concluded without satisfying all of the general and special conditions for validity are void and therefore, cannot be effective and cannot cause legal consequences. Furthermore, they cannot obtain validity afterwards.
